The 25-year-old is reported to be unhappy at having to play second fiddle to Lionel Messi at Barcelona.
Pique posted an image of himself with Neymar on Instagram last weekend with the caption "he stays", implying that the Barcelona players had convinced the Brazilian to stay at Camp Nou.
But the centre-back back later said that it was just his "intuition" that Neymar would not be leaving Barcelona this summer.
"Neymar and I we are very close and I want him to stay and I know the situation," Pique told ESPN on 29 July. "Right now he doesn't know what to do and we are trying to help him, the ones [on the team] that are more close to him to take the right decision.
"We will see. The tweet was about pushing him to stay. I want him to stay and we will see what happens."
Pique went on to suggest that Neymar would be swapping major titles for a bigger pay check if he left Barcelona for PSG.
"It depends on what he wants. He can be in all the clubs in all the world," the centre-back said. "He can be in Paris, Barcelona, Chelsea or City. All the clubs will want him. It's about your priorities. What do you want? Do you want more money? Do you want to win titles?
"It's happening here and it's happening in the NBA as well. There are some players that are not earning all the money that they deserve to win titles. So sometimes you have to take decisions in life and it's all about priorities."
